This paper considers (i) the robustness of the @t and Durbin-Watson bounds tests for first-order autocorrelation when disturbances in the linear regression model are heteroskedastic and (ii) the robustness of the Goldfeld-Quandt and Glejser tests for heteroskedasticity when the disturbances follow a first-order autoregressive scheme.
